> The position of dimension in rowkey is important for performance (both build and query);
But this message is not clear for a normal user. We'd better add instruction on the web GUI,
so that user knows to adjust it by some rule.
> In the rowkey part, adding:
> "Important: Dimension's positioin on HBase rowkey is critical for performance. You can
drag and drop to adjust the sequence. In short, put filtering dimension before non-filtering
dimension, and  put high cardinality dimension before low cardinality dimension."
